To all wlw/n t may concern: v

Be it known that I, JOSEPH HoRvA'rH, a subject of the Emperor of Austria-Hungary, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Filler-Cap and Lubricator, of which the following is a specication.

My invention relates to automatic lubricators especially adapted for automobiles and the engines thereof, and to self closing filler caps for such lubricators and for such other containers as may require a lling device that can be locked with its liquid re-4 ceiving aperture fully open against the tension of a spring.

One object of this invention is to provide a lubricator which will discharge no lubricant so long as it is at rest but will begin such discharge as soon as the machine upon which it is mounted begins to tremble and shake. Y Another object of this invention is to provide a valve within the lubricator to normally close the discharge passage therein, which valve will sway or roll sidewise when the device is shaken to partially uncover the discharge passage and thus permit the escape of a portion of the lubricant.

^ A further object of this invention is to provide one cylindrical member slidable're'lative to a stationary member concentric therewith, the movable member being formed with an aperture through which lubricant may be introduced into the device, one of these members being formed with a shoulder against which a projection on the other member rests while the said aperture is open, and to provide a spring for so holding these members relative to each other that said aperture in the one member will be covered by the other member when this is desired.

Vhile this lubricator is especially adapted for the spring shackles, propeller shaft bearings and steering mechanism of motor vehicles wherein the various parts to be lubri cated are subject to jars and shocks sutlicient to move the valve from its seat, it is equally useful in connection with any other machinery within similar movements may be imparted to the valve.

In the accompanying drawing, Figure 1 is a central vertical section of the outer stati onary member or body of the liller portion of this invention, the inner movable portion being in elevation and in lling position. Fig. 2 is an elevation of this device in closed position, portions` being broken away to show the interior of the parts. Fig. 3 is an elevation of a modified form of filler cap, a portion of the body being broken away. Figs. L1 and 5 are views of another modified form of filler cap in open and closed positions. Figs. 6 and 7 are views of a filler cap substantially as shown in Fig. 3 coinbined with a valve mechanism to control the discharge of the lubricant. Fig. 8 is a modified form of this lubricator.

Similar reference characters refer to like parts throughout the several views.

The devices shown in Figs. l to 5 are filler caps which may be employed inconnection with lubricators of any desired character or with any other receptacles to which liquids are to be conducted. In every case, a stationary member or body is designed to receive the liquid which is introduced through a filler opening in the movable member. In each case,'a spring is provided to move one member relative to the other and to cause the stationary member to close a filler opening in the movable member. In each case, one of the members is formed with a circumferential shoulder against which a projection on the other'member may engage to hold the movable member in suc-h position that the filler opening is unobstructed, and

the member thus formed with a shoulder isv also formed with a groove extending longitudinally from the shoulder in which the projection may travel when thel spring forces the movable member to the position where such opening shall be closed.

The devices which are shown in Figs. 1 to 5 inclusive vary in most of their details and my invention is therefore not limited to any of these details or to the proportions of the various parts. In Figs. 1 and 2 the cylindrical outer memberor body 10 may be formed with a threaded lower end y12 and with an inwardly projecting flange 17 at its upper end. The inner movable member or plunger 1l is provided'with a flange l5 at its lower end, between which and the flange 17 is a spring 16 which normally holds the parts in the positions shown in Fig. 2. The plunger is formed with a filler opening 13, a circumferential groove 18, and a longitudinal groove 19 that connects therewith. A flange or cap 14e on the upper end of the plunger may be knurled to assist in the turning of it. A pin 21 mounted in the flange 17 is slidable in the grooves 18 and 19.

lVhen the parts are to be set to receive the lubricant, the plunger 11 is lifted until the pin 2l reaches the groove 18, whereupon the plunger is turned to bring this pin below the circumferential shoulder forming the upper wall of this groove. The aperture 13 is fully open and lubricant or other liquid may bel introduced as desired. When the plunger is turned until the pin 21 reaches the groove 19 and then released, the spring 16 will force the parts to the positions shown in Fig. 2, when the opening 13 will be closed. A washer 22 of any desirable material then serves as a. packing ring to prevent the escape of the lubricant which may splash up within the plunger and through the opening 13. This' device may be employed as a. filler cap for automobile radiators and ,gasolene tanks.

In Fig. 3, the outer casing or body is substantially the same as in Figs. 1 and 2, but the plunger is of two diameters, the larger and lower portion 24 being provided Y with a longitudinal groove 25. The same head or cap 14 may be connected to the upper end of the smaller portion 22 of the plunger. The pin 21 is mounted at a lower point than in Figs. 1 and 2 and engages the shoulder 23 constituted by the lower edge of the hollow plunger. The operation of this device is substantially the same as thatV shown in Figs. 1 and 2.

TWhile the movable member is a plunge-r within a casing or body in Figs. l, 2 and 3, the movable member in Figs. 4 and 5 is a sleeve that is slidable on the body. The body 30 has an upper end 32 of larger diameter provided with a longitudinal groove 33. Therap 31 has its upper end closed and is provided with a filler opening 36 and an inwardly extending flange 34, formed preferably by bending in the lower edge of t-he cap. A spring 35 is mounted between the lower edge of the part 32 of the stationary member and the flange 34 on the cap. A projection 37 may be formed on the cap and slidable in they groove 33, but when the cap is elevated to uncover the opening 36, the cap may be turned so that this projection will rest on the shoulder 38 constituted b the upper edge of the part 32 of the body. 1When the parts are held in the position shown in Fig. 5, leakage around the upper edge of the part 32 may be prevented by the thin washer 39 shown next to the head of ing an enlarged lower portion 41 slidably i'ittinrv within the body 40 and provided with the filler opening 45 and the cap 46, are much the same as similar parts shown in Fig. 3, excepting that the body has a. closed lower end provided with a threaded hub 43 have ing a discharge passage 52. A collar 44 of sheet metal may 'be secured to the upper end of the body 40 by bending the flange 44 of the colla-r around the bead 40 on thev body. This collar serves as an abutment for the spring 47 thatV also bea-rsV against the shoulder formed by the upper end of the lower enlarged portion of the plunger. A cap 46 may be secured to the plunger and a packing ring 50 may prevent leakage between this cap and the collar 44. A pin 49 is adapted to slide in the groove or slot 48 in the plunger and to engage the shoulder 57 at the ,lower end of the plunger.

Mounted within the body is a valve 42 resting on the valve seat 51 at the upper end of the passage 52 and having an eXtension 53 projecting into this passa-ge to center the valve. The lubricant will flow down into and through this valve, sediment being retained in the chamber- 56. Y

Thel lubricator is filled through the opening 45 when the plunger is elevated to the position shown in Fig. 7, being held in that position by the pin 49. After the lubricator is filled, the cap 46 is turned until the pin 49 reaches the groove 48, after which the parts will be moved to the position shown in Fig. 6. As soon as themachinery is set in 100 motion, the shaking and jars thereof will slightly unseat the valve 42 and permit aV slight leakage into the passage 52. While the machinery is stationary, the valve will remain on its seat and prevent all escape of Y the lubricant. The flange 54 at the upper' edge of the valve will be of smaller diame# ter than the interior of the part 41 of the plunger, the difference in these diameters de! terminingthe extent of movement of the valve.

instead of the valve shown in Figs. 6 and 7, a ball valvev 65 may be employed, thisY valve rolling slightly as the body 40fvibrates and permitting the lubricant to escape. The 11,5 movements of the valves will increase andv V decrease in substantially the same ratio as similar Ymovements of the 4machinery onV which these lubricators are mounted and such movements will depend greatly upon 12.0 the .speed of the machinery, so that the feed of the lubricant will be substantially pro-l portioned to the demand therefor.
